Description

BODY OFVACUUM CLEANERAND HANDYTYPE CLEANER
[Technical Field]
The present invention relates to a body of vacuum cleaner and handy type cleaner that includes a dust container detachably mounted on a body of the vacuum cleaner and configured to perform vacuum cleaning via air suction in a detached state. [Background Art]
According to shapes and usage postures, vacuum cleaners can be generally classified into a canister type vacuum cleaner, which provides convenience in corner cleaning and movement while allowing easy replacement of a brush or a nozzle, and an upright type vacuum cleaner, which provides convenience in storage and allows easy cleaning of a large space.
Fig. 1 is a perspective view illustrating a conventional vacuum cleaner.
Referring to Fig. 1, the conventional vacuum cleaner generally includes a suction unit 11 which will be brought into close contact with a floor, a pipe 12 connected to the suction unit 11 and having a predetermined length, a handle 13 connected to the pipe 12, a hose 14 connected to the handle 13, and a body 20 connected to the handle 14.
The suction unit 11 is provided at a lower surface with wheels to suck up foreign matter while moving on the floor, and the pipe 12 and the handle 13 are used to move the suction unit 11 to desired locations. The pipe 12 and the hose 14 serve to guide air containing foreign matter into the body 20, which in turn sucks the air containing the foreign matter and collects the foreign matter while discharging filtered air to an outside of the body 20.
Fig. 2 is a schematic cross-sectional view of the body shown in Fig. 1. The body 20 is provided at a front side with a hose attaching part 21 for coupling with the hose 14. The body 20 has a dust collection unit 22 positioned in a central region and connected to the hose attaching part 21. Specifically, the dust collection unit 22 includes a dust container 24 that is inserted into an accommodation part 23 defined in the central region of the body 20 and has a filter 25 to filter foreign matter.
The dust container 24 is provided at an upper side with a knob 26 and is separated from the accommodation part 23 by means of a separation button 27 formed on the knob 26.
At this time, a motor 28 is positioned adjacent the accommodation part 23 inside the body 20 and driven by power supplied via a power cable 29.
Therefore, when the motor 28 is driven by power, air containing foreign matter is drawn into the dust container 24 and passes through the filter 25 in the dust container 24, so that the foreign matter is filtered by the filter 25 and collected in the container 24 while filtered air is discharged outside the vacuum cleaner.
Then, when filled with the foreign matter, the dust container 24 is separated from the insertion groove 24 by pushing the separation button 27, and opened to remove the foreign matter by means of a separate button.
However, since such a vacuum container has the motor installed inside the body, it is necessary to move the body when performing the vacuum operation at several locations on the floor.
Therefore, the conventional vacuum cleaner has problems in that the overall body must be moved even for corner vacuuming or partial vacuuming, and in that, in the case where a power cable has a short length, it must be plugged again into a wall socket near a vacuuming location. [Disclosure] [Technical Problem] The present invention has been made to solve the above problems, and an aspect of the present invention is to provide a vacuum cleaner that includes a detachable dust container capable of performing vacuum cleaning via suction of foreign matter in a detached state to permit a user to perform vacuum cleaning not only with the body of the vacuum cleaner but also with the dust container detached from the body, improving vacuuming efficiency.
